I know fellow community member Satochan (Patricia) uses CBD oil. She started a topic about her experience here: Hemp Extract Drops. She hasn’t visited in about a month, so if you have more questions you might want to send her a direct message.
Also, don’t feel obligated to attend a family get together that was planned without any consideration for your illness. You’re a grown woman and can make your own decisions. If you feel you must make an appearance, stop by briefly and leave. But above all, do what’s best for you.
